TOPICS ADDRESSED IN CENTENARIAN RESEARCH: A SCOPING REVIEW OF PUBLICATIONS SINCE 2000

Abstract Over the past decades, centenarians have increasingly attracted the attention of the research community. This development reflects the constant rise of the numbers of very old individuals, but also the need to better understand longevity mechanisms and what characterizes life at age 100. This scoping review provided an overview of trends in centenarian research from all disciplines since 2000, and identified the most frequently mentioned and neglected topics. Scientific articles meeting the following eligibility criteria were included: (1) publication between 2000 and 2021; (2) in English, French or German language; (3) study population of at least 95 years of age on average, or, for studies with larger age ranges, provision of specific insights for the 95+ group. Following the standard procedures for scoping reviews, we identified a total of N = 3955 articles. After removal of duplicates and exclusion due to unmet criteria, we used content coding to identify research themes of N = 1117 articles. Data confirmed that research articles offering findings on centenarians have increased substantially over the past two decades. Content coding led to 37 main topics: Most frequently, studies addressed higher-order topics such as physical, biological, and mental (e.g., cognitive), which were mostly investigated within disciplinary boundaries. Few multidisciplinary articles examined content domains in conjunction. The least investigated topics in centenarian research included the sub-domains of pain, stress, anxiety, and psychiatric disorders. In sum, findings inform the research community about the existing centenarian research, suggest that multidisciplinary publications are infrequent, and offer guidance for future studies.

studies were conducted to test development and evolution of an RT program, LifeBio Memory. A pilot study of the original LifeBio protocol was conducted with 238 residents in 16 Ohio nursing homes. Most residents (88%) indicated at posttest that they enjoyed telling their life stories, and 87% would recommend the program to other residents. However, manually gathering and processing life story data led to challenges with feasibility. Subsequently, novel software was developed to streamline the process using machine learning and artificial intelligence via a tablet application. Acceptability and feasibility were examined in two rounds, 9 months apart, of seven focus groups (n=35) conducted with PLWD, family care partners, and residential care staff. Audiotapes of the groups were transcribed; thematic data analysis was used to generate a list of recommended changes and showed high levels of acceptability and feasibility. Based on these results, it was determined that LifeBio Memory was preferred for obtaining life story information over the previous manual method (e.g., handwriting life story notes). Potential barriers to implementing the new platform in residential care settings were also identified. Implications include the importance of maintaining person-centered care practices when creating technological solutions to address PLWD needs.

MULTIPLE SCALES OF SOCIAL RELATIONS IN REMINISCENCE ACTIVITIES FOR OLDER ADULTS Jessica Robbins-Panko, Wayne State University, Detroit, Michigan, United States
Memory, especially autobiographical memory, is central to personhood in contemporary North America and Europe (Herskovits 1995). Cultivated practices of reminiscence, in which older adults are prompted to remember events and experiences from the past, can be pleasurable, meaningful, and therapeutic activities that shape personhood and contribute to wellbeing (Coleman, 1999;Sherman, 1987). Although reminiscence practices include both individual (e.g., Butler, 1963;Woods et al., 2018) andsocial (Hash et al., 2021;Sass et al., 2021) elements of remembering, less attention has focused on the myriad scales of social relations that are part of reminiscence activities. Moreover, the mechanisms through which reminiscence creates positive transformations remain unclear (Menn et al., 2020). Anthropological theories of personhood show that social relations at multiple spatiotemporal scales play key roles in transforming personhood (Carsten, 1995;Robbins, 2021), thus suggesting a nuanced framework within which to understand how social relations shape personhood and contribute to wellbeing for older adults. Drawing on a systematic review of interdisciplinary literature on reminiscence activities for older adults, this paper documents the multiple scales of social relations (interpersonal, institutional, regional, [trans]national) that are part of reminiscence activities, and interpretively analyzes their significance for personhood and wellbeing. Key findings of this study are: 1) collective memory plays an important role in reminiscence activities; and 2) fostering reminiscence activities that focus on meaningful elements of the shared past can promote wellbeing for older adults. These findings have implications for 1) refining gerontological theories of reminiscence, and 2) improving reminiscence-based practices for older adults.

THE TELLEGACY PROGRAM Jeremy Holloway, University of North Dakota, Fargo, North Dakota, United States
Emerging research displays how social isolation and loneliness (SIAL) before and during the Coronavirus pandemic are linked to health issues caused by SIAL. These issues are estimated to increase the risk of early death by 26 percent, the equivalency of smoking 15 cigarettes a day. The program started soon after the pandemic as an intergenerational program created to combat SIAL among older adults. University students, known as Legacy Builders, connect through virtual or via phone conversations to communicate meaningfully with the older adult. Students are prepared with a curriculum on mindfulness, SMART goal-setting, growth mindset, visualization goal-setting exercises, and reminiscence therapy as well as the skill and art of listening. At the end of the encounters, a legacy book is given to the older adult with a description of the older adult's life shared during their conversations with the Legacy Builder. The UCLA Loneliness Scale was utilized along with older adult self-reports. Sixteen residents in a memory care facility, ages 58 to 86, with multiple levels of dementia participated in the program of Summer 2021. The UCLA Loneliness Scale revealed that 13 of the 16 residents originally reported that they feel lonely or isolated. After 5 weeks of participation 7 out of the 16 residents report that they felt less lonely. Qualitative analysis showed improved perceptions of aging and an interest in Geriatrics among the student participants. These results also displayed positive older adult perceptions of the younger generation, and similar responses of the younger generation towards older adults.

Cognitive reserve (CR) refers to the capacity of the brain to withstand changes due to age or disease-related pathology, showing how flexibly and efficiently the individual makes use of available brain resources. This study aims to explore the contributions of the CR to understanding successful aging (SA).(Project-Conacyt-256589)Population based, random sample included n=656 community-dwelling older adults 60-years and older (mean age=72.8, SD=7.6 years, 58% women). CR was measured by their main indicators: education, life-long learning, being bilingual, participation, use of information and communications technology. Objective SA was operationalized as no important disease, no disability, physical functioning, cognitive functioning, and being actively engaged. Subjective was an appreciation if they considered themselves as successful agers. Sociodemographic and health data were also asked. Pearson´s correlation test and MANOVAs were performed.In total 11.2% met the criteria for SA, although 76% considered themselves as successful agers. CR was significantly related to subjective and objective criteria of SA(p<.000), except to no-important diseases. CR explains in general 20% of the variance in objective SA, specifically explains 28% of variance in the criteria of high cognitive function, 18% of the variance in disability, 11.3% of life engagement, 8% of physical functioning, and 2% of disease-free criteria. Also, CR explains 10% of the variance in subjective SA. This study has shown that CR the is related to SA, this set possible targets for cognitive interventions to promote resiliency of the brain not only for preventing cognitive pathologies, but also for encouraging successful and healthy aging in older adults.

OLDER ADULTS SHARE CHALLENGES IN THEIR LIFE STORY: SENSE OF PURPOSE AS A RESOURCE FOR RESILIENCE
Semper Habib 1 , Ameesha Narine 1 , Susan Bluck 2 , and Shubam Sharma 1 , 1. Kennesaw State University, Kennesaw,Georgia,United States,2. University of Florida,Gainesville,Florida,United States Maintaining a sense of purpose promotes mental and physical well-being in older adults (Musich et al., 2018). Drawing on one's sense of purpose is thus important for late life resilience. How older adults' sense of purpose manifests in their everyday lives remains understudied. This study used qualitative methods to amplify older adults' voices regarding purpose and resilience through analysis of their life stories. This study 1) explored what factors contribute to maintaining purpose in older adulthood, and 2) identified how older adults draw on their purpose during major challenges, particularly in the context of the COVID-19 pandemic. Eighteen older men and women (Mage = 79.1; including the youngold, old-old, and oldest-old) participated in semi-structured life story interviews that asked about participants' individual interpretations of purpose in their lives and their experiences navigating the COVID-19 pandemic. Thematic analysis was conducted using established methods (Braun & Clarke, 2012). To address the first research question, analyses revealed that older individuals largely maintain their purpose through engaging in acts of service to others, fostering connections with close others, and actively setting and achieving goals. Regarding the second question, older adults described how drawing on purpose through acts of service and connections with others fostered resilience through the COVID-19 pandemic. Overall, older adults' own expressions of their life stories illuminated how they are guided by purpose. Findings demonstrate the functionality of purpose in late life and how purpose can be practically fostered, specifically within the context of universally challenging experiences such as the COVID-19 pandemic.

BENEFITS OF VOLUNTEERING ON RESILIENCE WITH AGING: A CASE STUDY
Sanghee Lee 1 , Jinmoo Heo 2 , and Sanghee Chun 3 , 1. Korea University,Seoul,Republic of Korea,2. Yonsei University,Seoul,Republic of Korea,3. Brock University,St. Catharines,Ontario,Canada As the study of volunteering among older adults continues to evolve, questions of the benefits of volunteering are of growing interest to many researchers. Volunteering may develop resilience in older adults as it can serve as a coping strategy as they recover from adverse events or other life challenges. We explored the perceived benefits of volunteering on resilience in later life among older adults who perform Korean traditional dance on voluntary basis. We used a qualitative design with a case study method. In this study, older adults' volunteer dance performing was taken as a case. A case design enables researchers to understand social and cultural phenomenon in depth using a wide range of data collection and analysis methods. Thirteen volunteer performers of Korean traditional dance whose ages ranged between 61-74 years were recruited for in-depth interviews (11 females and 2 males). The analysis of the transcripts generated five themes related to the benefits of volunteering: (1) finding a sense of self-worth through serving others, (2) finding a sense of purpose, (3) experiencing gratitude, (4) renewing a younger self, and (5) building companionship. The findings of this study provided an
